It's definitely impressive-looking, but I doubt it will be as highly versatile as, say, Roll20. Maybe in another 10 years.
What gives other VTTs the edge is that you can use assets from any source you want. You can download maps and tokens online, or make your own, and use them in your game. But with something like this, you're pretty much limited to what the developers produce themselves, and it's just not going to be enough.
